Lack’s mastery of portraiture by now is obvious. His ability to not only capture a good likeness but to correctly create the illusion of form, mass and a sense of gravity has reached a high level of rendering. The original drawing was destroyed in the Atelier building fire, 1974.
Arthur Pier was Gammell’s (and Lack’s) doctor and commissioned Gammell to paint his portrait. Gammell made it a practice to do a pencil drawing study for his portraits. In this case, he gave Lack the responsibility of executing the pencil study for him. Lack continued the practice and also would include a color sketch.1
